The dream of fucking you and your mothers assholes while you each watched the other take my cock in the ass and then sucking it before it goes in another asshole until I cum in your mouth and you swap mouth to mouth with your mom ! xoxo

The mother part I find a little creepy, but sisters? Me and my twin sister have been fucking since we were teenagers, just fucking shouldn't be creepy at all, trying to get the pregnant on the other hand...
